Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of installing an escalator truss, and more particularly to a method of installing an escalator truss suitable for installing the escalator truss in an underground passage of a building.

[0002]

2. Description of the Related Art Conventionally, for example, when installing an escalator truss in an underground passage of a building, a wire is stretched along the escalator truss on the ceiling of the underground passage, and a winch is movably provided on the wire. The truss is divided into a plurality of parts along the longitudinal direction, and these divided parts are carried in a state of being suspended by using the winch and installed at a predetermined position in the underground passage.

[0003]

By the way, in the above-mentioned conventional installation method of the escalator truss, when the decorative plate for covering the ceiling of the underground passage is attached to the ceiling of the underground passage, or the ceiling of the underground passage is robust. If the beam member is not attached, there is a problem in that the wire or winch cannot be provided on the ceiling of this underground passage, and thus the conventional escalator truss installation method cannot be applied.

In general, in an escalator, since a machine room containing a driving machine and the like is provided in the vicinity of the upper portion of the escalator truss, the total length of the upper truss body may be set relatively large. In this way, when the total length of the upper truss body is set to be relatively large, even if the conventional escalator truss installation method described above can be applied,
When carrying the upper truss body along the upper surfaces of the intermediate and lower truss bodies, there was a concern that the upper truss body would collide with the upper surfaces of the intermediate and lower truss bodies or the ceiling of the underground passage. .

The present invention has been made in view of the actual situation in the prior art as described above, and an object thereof is to smoothly carry an escalator truss to a predetermined position in an underground passage, and to form a lower truss body and an intermediate truss of the escalator truss. An object of the present invention is to provide a method of installing an escalator truss capable of arranging the body and the upper truss body in order from the lower side to the upper side in the underground passage.

[0006]

In order to achieve this object, the present invention divides an escalator truss consisting of an upper truss body, an intermediate truss body and a lower truss body into a plurality of parts, and sequentially carries in these parts. In the method of installing the escalator truss to be installed at a predetermined position, the first step of providing a lifting device at both the lower entrance and the upper entrance of the escalator, and the upper truss body from the lower entrance side. The second step of carrying in and moving to the upper entrance / exit side by the operation of the lifting device, and carrying in the lower truss body from the lower entrance / exit side and moving it to a predetermined position near the lower entrance / exit And a third step of installing the intermediate truss body from the lower entrance / exit side and sliding it to a predetermined position diagonally above the lower truss body for installation. When, it is to the upper truss member to the structure and a fifth step of installing at a predetermined position between the upper end of the intermediate truss member and the upper entrance is moved from the upper entrance side.

[0007]

As described above, according to the present invention, as a first step, the lifting devices are provided at both the lower entrance and the upper entrance of the escalator, and the upper truss body is installed from the lower entrance and exit side in the second step. After carrying in and moving to the upper entrance / exit side, in the third step, the lower truss body is carried in and installed at a predetermined position near the lower entrance / exit, and as the fourth step, the intermediate truss body is installed from the lower entrance / exit side. Since the upper truss body is installed at an obliquely upper position of the lower truss body and then installed at an obliquely upper position of the intermediate truss body as a fifth step, these lower truss body, intermediate truss body and upper truss body are installed. The underground passages can be arranged in order from bottom to top.

Further, the second step is performed prior to the third step and the fourth step, and in this second step, the upper truss body is carried in from the lower entrance / exit side and moved to the upper entrance / exit side. At this time, since the intermediate truss body and the lower truss body are not installed in the underground passage and a large space is formed in the vertical direction in the underground passage, the total length dimension of the upper truss body is relatively large. Even in such a case, the upper truss body can be smoothly carried into a predetermined position in the underground passage without colliding the upper truss body with the ceiling of the underground passage or the like.
